Overview
The CEL PS2832-4-A is a high-isolation voltage, four-element Darlington output optocoupler housed in a 16-pin SSOP package. It provides 2500Vrms isolation between input and output channels. The device features a maximum collector-emitter voltage of 300V and a maximum collector current of 60mA per channel. It operates with a forward voltage of approximately 1.4V. This component is designed for applications requiring robust electrical isolation and multi-channel signal transmission.
Feature Summary
- Four independent Darlington output channels within a single compact package
- High isolation voltage capability of 2500Vrms for enhanced safety
- High collector-to-emitter voltage rating of 300V
- Compliant with UL and VDE safety standards
Applications
- Industrial automation control systems
- Power supply feedback loops
- Multi-channel signal isolation interfaces
- Motor drive circuits
Procurement Notes
Verify the specific suffix (e.g., -A) against the manufacturer's current datasheet to confirm pinout and packaging details. Confirm RoHS compliance status as manufacturing processes may evolve. Check for obsolete status or lifecycle changes before finalizing procurement plans.
Selection Notes
Select this component when multiple isolated channels are required in a space-constrained design. Ensure the load current does not exceed the 60mA limit per channel. Verify that the 300V collector-emitter voltage rating meets the circuit requirements. Consider the 16-pin SSOP footprint for PCB layout compatibility.
Part Context
This part belongs to the CEL PS2832 series of multi-optocouplers. It shares the core architecture with variants like PS2832-4 but may differ in packaging or compliance markings based on the suffix. The series is known for high isolation and reliability in industrial environments.
Replacement Considerations
Direct substitutes include other 4-channel Darlington optocouplers with similar isolation ratings. Verify pin compatibility and current transfer ratio before substitution. Consult the manufacturer's cross-reference guide for approved alternatives.
